Viessmann boilers

The Viessmann Group is one of the leading international manufactures of heating, cooling and climate control technology. Founded in 1917, the family business maintains a staff of approximately 11,400 employees and generates 2.1 billion Euro in annual group turnover.

Viessmann has launched a new range of gas-fired condensing boilers which are notable for being more cost-effective and take much less time to install.

Available as both system and combination boilers and in outputs of 19-35kW, the Vitodens 100-W condensing boiler can be installed in a variety of locations and is ideally suited for homes where space is at a premium, which makes the unit a perfect solution for social housing.

Viessmann have delivered a new range of condensing boilers which meet the demands of both consumers and installers. Not only is installation simpler and quicker and therefore more cost-effective – aided by condense connections and pressure relief valves being combined – the unit meets consumer demand for high performance and ease of use.

Other stand-out features and benefits of the range include:

Smaller design – the largest 35kW model is 350mm by 700mm

Weight has been reduced by up to 4kg thanks to a new case design

It’s one of the quietest boilers in the product group

Low emission combustion

Features a maximum flue length of 19 metres

A user control interface with LCD screen and digital plug-in controls enables wireless adjustment of settings in conjunction with a Vitotrol 100 controller

Service time is reduced as parts are easily accessible from the front of the boiler

The Vitodens 100-W achieves a standard seasonal efficiency of up to 90.4% thanks to Viessmann’s Inox-radical German made heat exchanger, which benefits from a 10 year warranty. Featuring a stainless steel heating surface condensate can run off downwards which creates a permanent self-cleaning effect to achieve a longer service life.

Consumers can achieve additional savings of up to 12% – around £88 a year – by connecting the unit to an outdoor temperature sensor which automatically switches to weather compensation mode.

Fred ButcherNew Boiler InstallationReading, Berkshire

Simon installed a boiler for me. He takes an efficient, no-nonsense approach to his work. He inspired confidence in his know-how and integrity when giving a quotation. Working solidly, Simon completed the installation in the time arranged and left the property clean and tidy, replacing floorboards with care and making good external paintwork after necessary alterations. Simon explains things clearly, and displays sincerity about being available in the unlikely event that any problems arise.

Simon did a great job replacing our very tired and broken old boiler. He arrived when he said he would, explained what needed doing and why and kept me informed along the way. He was extremely neat and tidy, courteous and great rates too! I will be calling Simon next time we need any work doing and would absolutely recommend him to anyone else.
